Sinterability of TiO2-coated fine Ni powder

In order to control the sinterability of fine Ni powder for internal electrodes of multilayer ceramic capacitors application, Ni particles were coated with TiO2 by a homogeneous precipitation method. TiO2 coating suppressed considerably the sinterability of Ni powder. TiO2 powder additions also showed a suppressing effect on the sinterability of Ni powder, but in lesser extent if compared to the TiO2 coating.
